The guys over at iTweakiOS have release a pair of cracked carrier updates for AT&T and Sprint that promise to bring faster speeds and better overall signals to iPhone. The updates don't require a jailbreak, but you'll need an iPhone 4S or iPhone 5 to take advantage of them.

Chrome: We've probably all made a regrettable, impulsive buy before. What if there was an app that automatically put such purchases into perspective? There is, and it's called the Dictionary of Numbers.

Android: We've covered several Android alarm clocks, but WakeVoice is different. Instead of waking up to music, WakeVoice rings, then speaks to you when it's time to get up. It can play a personalized message, read the news headlines, or fill you in on the weather for the day, all while you drag yourself out of bed.

Linux: If you've built the home theater of your dreams and it's powered by XBMC, Maraschino is a simple, open-source front-end that's web-accessible and makes managing your media and downloads super easy.

iPad: The looming shutdown of Google Reader is a great opportunity to look at new RSS apps to go along with your new syncing service of choice. If you like to keep up with news on your iPad, nothing matches the powerful options available in Mr. Reader.

Android: We all know that screen brightness has a huge effect on your phone's battery life, but Android's built in auto-brightness setting isn't always accurate, and doesn't offer anything in the way of customization. Velis Auto Brightness on the other hand oozes customizability, and gives you more control than you could ever need over your screen's brightness.
